DUST COLLECTING AND ABSORBING SUBSTANCE.

Specification of Letters Patent.

Patented Feb. 23, 1909.

Application filed August 26, 1908. Serial No. 450,289.

have invented certain new and useful Improvements in Dust Collecting andAbsorbing Substances, of which the following is a specification.

This improved dust collecting and absorbing substance is primarilyadapted for collecting dust, dirt and other impurities found uponfloors, tiling, linoleum, rugs, carpets, etc., the same serving as anantiseptic or germicide.

My invention relates to a mineral wax and which I use to form a coveringand binder for a base (composed refer-ably of salt, sawdust and sand,although other dry granular sub stances can be employed), which, whencovered erfectly With the above referred to wax, "orms a valuablesweeping and cleaning preparation that can be passed or drawn overthefloor surface without a itating dust, dirt and lint found on same andcausing the dust to rise and float in the air; but the sticky waxsurface gathers and immediately absorbs all of the dust, dirt and lint.Another great improvement or advantage it has over any other materialever employed for a similar purpose is its non-volatile sticky naturewhich will not dry out with age and will not grease or stainthe floorsurface, even if it is allowed to remain on same for months. This cannotbe said of any other material that has been used for a similar pur ose.

Any kind of pa or or fiber sac; or container can be user for packing thefinished roduct as it will not spot or stain, thus efiecting a greatsaving in the cost of the container used for packing.

The filler or covering matter in this instance is obtained from thetailings of mineral oil after the inflammable gases and volatile liquidhydrocarbon compounds of the araffin series have been first driven off,thus eaving a sticky non-oily wax-like substance that is im ervious toatmospheric and weather con itions.

A suitable color can, if desired, be added to the filler or coveringmatter after the same has been heated, so as to convert it into a liquidpreparatory to depositing it with the base. This coloring may be ofburnt umber or any mineral pigment or anilin color, and when poured ordeposited upon the base serves to give the resultant product both anattractive and uniform appearance.

The various ingredients of the base are thoroughly agitated and mixed ina revolving mixer or chamber, so as to convert it into a uniformcompound. The non-oily filler or covering matter is then warmed by meansof steam coils or otherwise, so as to convert it into a liquid, in whichcondition it is poured into the mixing chamber upon the basic materialswith which it is thoroughly impregnated, so that the various basicparticles are thoroughly coated or covered with the nonoily wax-likesubstance, which forms the filler or covering. After the basic particleshave been thoroughly coated or covered with the aforesaid non-oilywax-like covering a suitable antiseptic and deodorant, is poured intothe revoluble mixer just before removing the finished product from themixing chamber. The resultant product ossesses the qualities ofcollecting and a sorbing dust, dirt and other impurities, and, owing toits antiseptic properties, is especially useful for sanitary purposes,leaving the premises in a clean and healthful condition.

Oil of mirbane, or any other similar essential oil, can be employed as adeodorant in combination with this improved dust collecting andabsorbing substance.

What I claim as new and desire to secure by Letters Patent is:

A dust collecting and absorbing substance having a base capable ofretaining a nonvolatile permanent covering, and nongreasy tailings ofmineral oil, forming a permanent covering therefor, substantially asdescribed.
